Module A - Slide 18


Let me just quickly go through the required APS features in the 2009 MUTCD. They include a pushbutton locator tone, tactile arrow, audible walk indication and a vibrotactile walk indication. The audible walk indication is specified as a percussive tone; an arrow on the pushbutton vibrates to provide the vibrotactile walk indication. The location of APS pushbuttons is specified. They should be as close as possible to the crosswalk line furthest from the center of the intersection and as close as possible to the curb ramp. In addition, there is new specific guidance for location of all pushbuttons (pedestrian detectors) in 4E.08
